Wi-Fi Tags

Wi-Fi Tags

The Wi-Fi Tags are a key component of the Airetrak solution. Wi-Fi tags are small devices that are attached to key assets and resources to allow their location to be determined on the system. The Wi-Fi tags broadcast out a signal which is picked up directly by the wireless LAN and used to calculate the location. This allows the asset to be identified and the location displayed on the system.

Wi-Fi tags can be attached to physical assets or people using a number of options such as adhesive pads, tie wrap and wristbands. The tags are powered by a battery which can last up to 7 years, depending on the frequency of the broadcast.

The Airetrak solution is tag independent and is designed to work with any 802.11 compatible Wi-Fi tags.
Airetrak recommends the Aeroscout range of Wi-Fi tags which are the industry's best-selling and most widely-deployed Wi-Fi tag.

Wi-Fi tags have a range of features and options which include:

• Motion Sensors
  Built-in motion sensor enable the tags to send motion status to users of the tracking system. This can be used to indicate to ResourceView when an asset is in use or alarm when an asset is potentially being stolen.
   
• Choke Point Detection
  The Wi-Fi tags contain a small magnetic sensor which can be ‘excited’ using a fixed position ‘exciter’. This enables the tag position to be determined to a high accuracy (such as a shelf or small room) and to trigger immediate alerts as it passes through a choke point (such as a doorway)
   
• Call Button
  The Wi-Fi tags can contain a call button which sends configurable alerts to ResourceView. This can be used to indicate an emergency situation (such as a panic attack) or to indicate a maintenance or cleaning requirement (such as a hospital bed has been cleaned and is ready for use)
   
• Anti-Tamper
  The tag detachment detection feature alerts ResourceView when the tag has been removed from the asset it has been attached to. This can be used in anti-theft situations
   
• Telemetry functions
  The Wi-Fi tags can monitor environmental conditions such as temperature, pressure and gas and can deliver the measurements and can trigger alerts based on reaching a configurable threshold.
   
• Power Indicator
  The Wi-Fi tags can indicate battery status and alert when battery levels fall below a certain point
   
• Compatibility and Non-interference
  As the Wi-Fi tags operate at the Wi-Fi 802.11 2.4GHz frequency there is no interference with other wireless equipment, making the tags safe for use with such sensitive equipment as medical devices in a hospital
   
• Rugged Design
  The Wi-Fi tags are designed to handle both indoor and outdoor environments and are water, dust and weather (heat, cold, humidity) resistant. They can be cleaned using the normal chemicals used in the hospital environment
